摘　　要： 分析河西内陆河流域的水循环二元结构,揭示了各自水量转化特点及相互联系;对山区消耗水量,走廊盆地人工绿洲建设引起的地表水与地下水转化的变化和消耗水量的增加,以及内陆河下游水分亏缺问题作了评价.提出了理解流域水循环整体概念,评价山前平原水资源消耗的影响,在流域水资源开发利用中改善水资源转化. In this paper, the formation of water resources in mountain areas, scatter and disappear of water resources in plain areas and duality composition of water resources in artificial oases are discussed, and the water transformation features and interrelation in the water cycle of inland river basins in Hexi Corridor are revealed, through an analysis of the key links of water cycle in the inland in Northwest China. Water consumption in mountain areas, transformation between surface water and ground water, water consumption increase caused by artificial oases construction in the Hexi Corridor, and water shortage in the lower streams in inland river basins are quantitatively analyzed. Finally, an entire concept of water cycle is put forwards to evaluate the effect of water consumption in the front plains, and a conclusion is made of improving water transformation in sustainable utilization of water resources in Hexi inland river basins during the development of the western region of China.
